Solar-powered cooling system

Номер: US20140060093A1
Автор: Joseph C. Farmer
Принадлежит: Lawrence Livermore National Security LLC

A solar-powered adsorption-desorption refrigeration and air conditioning system that uses nanostructural materials such as aerogels, zeolites, and sol gels as the adsorptive media. Refrigerant molecules are adsorbed on the high surface area of the nanostructural material while the material is at a relatively low temperature, perhaps at night. During daylight hours, when the nanostructural materials is heated by the sun, the refrigerant are thermally desorbed from the surface of the aerogel, thereby creating a pressurized gas phase in the vessel that contains the aerogel. This solar-driven pressurization forces the heated gaseous refrigerant through a condenser, followed by an expansion valve. In the condenser, heat is removed from the refrigerant, first by circulating air or water. Eventually, the cooled gaseous refrigerant expands isenthalpically through a throttle valve into an evaporator, in a fashion similar to that in more conventional vapor recompression systems.

Автор: GENTRY Todd
Принадлежит: HyperBorean, Inc.

Embodiments of the present invention reduce the amount of energy required to operate air-conditioners and refrigerators by providing a vapor-compression system that harnesses a low- or no-cost source of energy, namely, heat, and uses the harnessed heat to power a new kind of compressor, called a “burst compressor” and a new kind of pump, called a “vapor pump.” The heat-driven burst compressor pressurizes the refrigerant, while also providing “push and pull” vapor refrigerant to the vapor pump. The vapor pump, actuated by the high pressure refrigerant in gaseous form provided by the burst compressor, is configured to pump a combination of gaseous, vaporous and liquid refrigerant out of the receiver tank and inject that low pressure refrigerant mix into the burst compressor, where it is heated to change the state of the refrigerant to a heated, pressurized gas. Then the heated, pressurized gas is released in bursts into the other components of the vapor compression cycle. Thus, embodiments of the present invention use heat to provide cold. Because of this arrangement, vapor-compression systems constructed and arranged to operate according to embodiments of the present invention are able to provide air-conditioning and/or refrigeration much more efficiently and with much less expense than traditional vapor compression systems for air-conditioning and refrigeration. 1.

When a defrosting of an exterior heat exchanger is performed, a refrigeration cycle device switches to a refrigerant circuit, in which a refrigerant discharged from a compressor dissipates its heat at an interior condenser and the exterior heat exchanger, the refrigerant dissipating the heat at the interior condenser and the exterior heat exchanger is decompressed by a battery expansion valve, and then the refrigerant decompressed by the battery expansion valve evaporates at a battery heat exchanger to be drawn into the compressor. Thus, the heat absorbed by the refrigerant from a secondary battery via a battery ventilation air can be used to defrost the exterior heat exchanger, while sufficiently heating the interior ventilation air at the interior condenser.
